Slackware 15.0 64 - ELILO freezes after improper upgrade via slackpkg

Hello and HNY!
I dared to do

Code:

slackpkg upgrade-all

-> it went without any issues
and then let config files be overwritten. I assume also kernel files were upgraded and now i cannot boot. I think i have ELILO. I was able to boot from installation media where i think it was possible via grub. So now "normal boot" is not possible. Please help me fix that. Some more information:

Code:

        initrd=initrd.gz

        read-only

        append="root=/dev/nvme0n1p3 vga=normal ro"

Please let me know what else you need as information in order to fix it, thanks!

If you can boot the installed system using the installation media, then you should be able to run "eliloconfig" and follow the bouncing ball to fix everything.

Hello @rkelsen, i tried running

Code:

eliloconfig

, all went without errors, an entry was replaced but i still cannot boot.
In the attached files you can see where bootloader freezes and which entries are available for selection via installation usb. The system gets loaded when i select /boot/vmlinuz-huge-5.15.80 (although not sure if this should be the proper choice).

Could you post your elilo.conf file? That should help us figure out what is wrong.

It appears from your fist pic pasted, the huge kernel is loading, and there is an ititrd.gz file.

Did you create a new one after the upgrade to the 5.15.80 kernel?

If in fact you are trying to loade huge, you shoud not need an initrd.gz file. I rare situations, one can be needed.

I did not create a new elilo.conf after doing upgrade-all via slackpkg. I just told the script to overwrite the new config files after it was done. What it did, i do not know. I also tried to run eliloconfig which ran without any issues but my system still cannot boot.

Clearly, you are trying to load the huge kernel, and an initrd.gz of unknown contents.

Edit the elilo.conf file by hand. Comment out the initrd= line, place at least one # sign at teh beginning of the line. See if it will boot then.

I can post a working elilo.conf file if you would like.

Could you also post an ls -l of your /boot/efi/EFI/Slackware directory.

Hello even, with commented out line before initrd booting is not possible, also please see above desired output of directory. Thanks for trying to help me.

Please post the contents of your /boot/efi/EFI/Slackare/ directory. A ls -al command should do.

Here, for reference is nine. Things to check, do you see in yours the correct kernel you wna to boot to in in yours? Does the elilo.efi file look to be the same size as the one in boot? It should match elilo-x86_64.efi in /boot. The initrd.gz file, have you generated another one and copied to /boot/efi/EFI/Slackare/ after the kernel upgrade? Check the size for comparison.

Also for comparison, here is the contents of my elilo.conf file. The main thing to look at are lines 9 to 12. You will see I use the full name of the kernel I want to boot, rather than the sym link. This is not mandatory, but for me takes any confusion as to what will happen; with the minor problem when I change kernels, I have to edit this file by hand.

Hope this helps.

BTW, if you realy have the generic kernel copied, and you need it to boot, you will need an initrd.gz file, so you can un-comment the line for it in this case.

I would try a quick grub bootlader swap just to discard an elilo bug

Copy EFI/bootx64.efi from usb installer to /boot/efi/EFI/Slackware/grub.efi

create a simple /boot/efi/EFI/Slackware/grub.cfg config file:

Code:

set default="0"

set timeout="5"

set hidden_timeout_quiet=false



menuentry "Slackware 15.0" {

  echo "Loading vmlinuz.  Please wait..."

  linux /EFI/BOOT/vmlinuz root=/dev/nvme0n1p3 ro

  initrd /EFI/BOOT/initrd.gz

}

Then use efibootmgr and add an entry for /EFI/Slackare/grub.efi

The size of /boot/efi/EFI/Slackware/vmlinuz is the same as /boot/vmlinuz-generic-5.15.80, so it's the generic one which needs initrd. The symbolic links in /boot, for example vmlinuz-generic, are dated 'Dec 31 15:06', so the kernel was upgraded then. But initrd.gz is older 'Dec 31 10:00'. You need to build a new initrd.gz after upgrading kernel, and copy it to /boot/efi/EFI/Slackware.

What's in /boot is of no matter when the system is booting with EFI, since the root partition isn't even loaded at that point. elilo, by your configs, is grabbing /efi/EFI/Slackware/vmlinuz and trying to run that with /efi/EFI/Slackware/initrd.gz. By the dates (Nov, Dec) of those files, that might not be what you want. You can use 'file' to tell you the version of a kernel bootable image. Your initrd better match it. You might also want to check 'efibootmgr' to make sure it has an entry that actually points to elilo.efi like so:

Code:

Boot0001* Slackware HD(1,GPT,1d39afc6-46db-4550-b122-74c8381926f3,0x800,0x82000)/File(\EFI\SLACKWARE\ELILO.EFI)

When this happens to me, I boot with a USB stick and pass "mount root=/dev/sda1" as a boot parameter to get the machine up...

...and then I 'eliloconfig' to fix elilo

To fix this in the future, I have started running updates with my little script:

Code:

#!/bin/bash

slackpkg update

slackpkg install-new

slackpkg upgrade-all

lilo

eliloconfig

Thanks to all who posted!
What i did was that i found that sample script

/usr/share/mkinitrd/mkinitrd_command_generator.sh

i ran it and whatever was suggested i ran that command. After that i was able to boot without USB disk.
